# PTE DI #26: Mechanism of Wave Energy Conversion

Describe Image #26 - Level 3 - Feeds Speaking

> Look at the given Image below in 25 seconds, please speak into the microphone and describe the details what the Image is showing. You will have 40 seconds to give your response.

## Answer

The diagrams illustrate how electricity is produced using sea waves. In diagram A, the rising wave pushes air through a column, spinning the turbine to generate electricity. In diagram B, as the wave recedes, air flows back through the turbine in the same direction, continuing power generation. This bidirectional airflow ensures continuous turbine rotation, efficiently converting wave motion into renewable electrical energy.

## Explanation

A strong response identifies the process flow, starting with the wave entering the chamber, forcing air through the column, and spinning the turbine to generate electricity in both phases.

## Hints

- Start by identifying the main subject and the two distinct stages shown in the diagram.
- Describe how the movement of the wave affects the air pressure within the chamber and column.
